         5 . The absorbent article according to  claim 4 , including a feces stopping member in an upper surface or in a vicinity of a front end of the second leak preventer. 
     
     
         6 . The absorbent article according to  claim 4 , including a main body bonding member bonding to the first leak preventer, the absorber, or the second leak preventer at a lower end of the bridging member. 
     
     
         7 . The absorbent article according to  claim 2 , in which the bridging member and the main body bonding member are formed of a same material. 
     
     
         8 . The absorbent article according to  claim 2 , in which the bridging member and/or the main body bonding member is stretchable. 
     
     
         9 . An absorbent article according to  claim 1 , in which the side members are formed of a pair of extended parts of the first leak preventer formed integrally with the base part and a pair of peripheral shape retaining members provided along peripheries of the extended parts. 
     
     
         10 . The absorbent article according to  claim 1 , in which the side members have stretchability. 
     
     
         11 . The absorbent article according to  claim 10 , in which the side members are leg gathers provided on right and left ends of the base part. 
     
     
         12 . The absorbent article according to  claim 11 , in which the leg gathers are standing leg gathers each including a leg part bonded to the base part and formed of a non-woven fabric, and a head part bonded to the leg part and including an elastic body. 
     
     
         13 . The absorbent article according to  claim 1 , in which: the bridging member includes a stretchable area in a center part and non-stretchable areas on right and left sides of the stretchable area; and the bridging member is bonded to the side members in the non-stretchable areas. 
     
     
         14 . The absorbent article according to  claim 1 , in which: the side members are each stretchable; the bridging member is non-stretchable; and the side members are bonded to the bridging member so that the bridging member becomes stretchable in a lateral direction.
